The results show that shallow groundwater and deep groundwater are polluted to different degrees, and the pollution of shallow groundwater is very serious. In terms of distribution space, the monitoring well in the downstream direction of golf course is the most seriously polluted.展开更多

文摘Taking a golf course as the object of investigation, this paper monitors the groundwater distribution of the course, uses the assessment method of groundwater quality and pollution status to evaluate the groundwater foundation of the course. The results show that shallow groundwater and deep groundwater are polluted to different degrees, and the pollution of shallow groundwater is very serious. In terms of distribution space, the monitoring well in the downstream direction of golf course is the most seriously polluted.
